Selling a house in Vienna and Lower Austria – process, specifics, costs

Key points

• Compared with a flat, plot boundaries, zoning, surveying and an energy certificate for the whole building come into play.
• An energy certificate is mandatory when selling (Energy Certificate Presentation Act 2012): at most 10 years old, handed over no later than 14 days after the contract.
• Some houses do not stand on their own land but as a Superädifikat or on a building right – this changes financing, tax and the contract.
• In Lower Austria, buyers from non-EU countries need approval from the land transfer authority (NÖ GVG 2007); the application is due within 3 months of the contract. EU and EEA citizens are treated like Austrians.
• Seller's costs: commission 3% plus 20% VAT, energy certificate, deletion of old mortgages; with a gain, possibly real estate income tax (ImmoESt).
• Timing: at a market price usually 3 to 6 months from the first valuation to handover (ImmoLöwin's experience).

How selling a house differs from selling a flat

A house is legally and practically more complex than a flat because the land is part of the deal:

• Boundaries and surveying: unclear or outdated boundaries (e.g. after extensions or a new fence) should be clarified before the sale; a survey plan by a chartered engineer (Ziviltechniker) gives buyer and bank certainty.
• Zoning (Flächenwidmung): decides whether and how the plot may be built on. Buyers and banks regularly check it before approving finance.
• Energy certificate: covers the whole building (see below).
• Release of encumbrances: existing mortgages must be deleted before or at handover.

Superädifikat and building right

A Superädifikat is a building erected on someone else's land; the owner of the house does not own the plot but usually uses it as a tenant. Financing, transfer tax and the contract therefore work differently from a normal house purchase: the building is sold, together with an existing or new lease of the land. Similar but separately regulated is the building right (Baurecht) under the Building Rights Act – a registered, time-limited right to build on someone else's land.

Example from ImmoLöwin's practice: for one property in Langenzersdorf, the house stands as a Superädifikat on land owned by Klosterneuburg Abbey (Stift Klosterneuburg). The buyer acquires the building and signs a new open-ended land lease with the abbey – with an index-linked rent and a long waiver of termination by the landowner. Such structures are not unusual around Vienna and need separate checking before a purchase offer.

Energy certificate when selling a house

Under the 2012 Energy Certificate Presentation Act, the seller must show the buyer an energy certificate before the buyer makes their contractual declaration and hand it over no later than 14 days after the contract. The certificate may be at most 10 years old. Even the advertisement must state the heating demand and the overall energy efficiency factor – an obligation for seller and agent alike. Exception: buildings objectively ripe for demolition, if the advertisement says so and the buyer undertakes to demolish.

Land transfer in Lower Austria: buyers from non-EU countries

If a house in Lower Austria is sold to a foreign person, the buyer needs approval from the Lower Austrian land transfer authority before the land register entry. This does not apply to nationals treated like Austrians under EU law, such as EU and EEA citizens (§ 15 NÖ GVG 2007):

For the seller this mainly means: plan in extra time – a sale to a buyer from a non-EU country can only be registered once approved. What else foreign buyers need to know is in Buying property in Austria as a foreigner.

How long the sale takes

From ImmoLöwin's practice: with a correctly valued market price, a sale usually takes 3 to 6 months from the first valuation to handover. The condition is decisive: an inflated asking price tends to lengthen the process rather than create room for negotiation.

Buyers are better informed than ever: they check offers with AI assistants and compare them within minutes with Statistik Austria data, portals and valuation calculators. An inflated asking price therefore creates no room for negotiation; it drops the property from the shortlist – it sits on the market and is later often sold below what it could have achieved. We therefore expressly advise against overpricing; a realistic first valuation is the most important lever for the time to sale. A first estimate comes from the value calculator.
